Abstract

The invention discloses an energy storage charging and discharging controller with a warming function. The controller comprises a charging and discharging controller (1), a cell heating switch circuit (2) and a cell temperature measurement circuit (3), and is characterized in that the charging and discharging controller (1) is connected with the cell heating switch circuit (2) and the cell temperature measurement circuit (3); a cell warming control circuit is formed by a temperature sampling circuit (8) and a temperature measurement probe port (9); the temperature measurement probe port can be externally connected with a temperature probe; and the cell heating switch can be externally connected with a warming wire. The controller is advantageous in that disadvantages in the prior art are overcome; and the controller is proper and novel in structure design.

Description

technical field [0001] The invention relates to an energy storage charge and discharge controller, in particular to an energy storage charge and discharge controller with a heating function. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. With the development of science and technology, lithium batteries have become the mainstream now. Lithium-ion batteries have been widely used in portable electrical appliances such as laptops, cameras, and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources of electric vehicles in the 21st century, and will be applied in artificial satellites, aerospace and energy storage. With the shortage of energy and the pressure of the world's environmental ...
